MEANS FOR CONNECTING YOKlE-STRAl?$ TO DRAW-BARS FOR RAILWAY-CARS.

To all whom it may concernr f, i

Be it known that 1, WILLIAM A. Games,

a citizen of theUnitedflState's, residing at.

Chicago, in the county of cookand State of Illinois, have invented a certain new and useful Improvement in Meansjfor Connect ing Yoke-Straps to Draw-Bars for Railway- Cars, of which the following-1s a fulhclear, concise, and exact description, reference being had to the accompanying drawlngs forming a part of this specification.

My invention relates to improvements in means for connecting yoke straps todrawbars for railway cars.

The object of my invention is to provide a simple and etlicient means for connecting 'ng a part of this specification, Figure 1 1s a side elevation, partly in vertical longitudmal sect1on,of a

" draw-bar and yoke-strap with my improved provided strap. 16

connecting means applied; Fig. 2 is a front end view of the structure; and Fig. 3 is a perspective view of one of the retaining clevises. I l v Referring to the drawings, the numeral indicates ayoke-strap of usual construction,

having an upper limb 11, a lower limb 12, a rear connecting member 13, and upper and lower in-turned gibs 14 and 15, respectively, at the forward free ends of the type having a shank 160 and a butt 17 the r i I butt being provided with upper and lower at shoulders 18 and 19,-respectively, adapt- -ed to be engaged by the upper and lower dill draw-bar is also provided with the usual spaced apart.,vertical rivet holes 2020,

and the yoke strap is provided in its upper limb with the usual rivet holes 21-21, and in the lower limb with the rivet holes 22-22 registering, when the yoke-and draw-bar are assembled, with the rivet holes in the draw-bar.

Instead of employing rivets to secure the draw-bar. and yokestrap together, ll employ a readily detachable clevises passes around one-limb of the yoke Specifidation of. Letters Patent.

and straddles the draw-barf the other leg passes about the other limb of the yoke and likewise straddles the draw-bar, the legs of said clevises being suitably overlapped and being provided in their overlapping portions with the transverse perforations 27-,27 which register with-each other and with the usual transverse coupler key slot 28. -11

coupler key 29 passes through both clevises and the draw-bar, and serves: to hold the clevises in their assembled. position upon -the draw-bar and yoke, as-well as to form a connection between the clevises and the drawandthe yoke-strap is found in the integral bar. A further I connection between the a pins -30-' 30 .with which the inner 'face ofeach transverse member 25 of the clevises is provided, the said pins being adapted to pass through the usual rivet holes in the adjacent limb of the yoke-strap and to enter, the adjacent portions of the usual rivet holes provided in the draw-bar.

In assembling the parts, placed upon the draw-bar, the upperv and lower clevises are then placed in their positions with the pins entering rivet holes in the yoke-strap anddraw-bar, as hereinbefore described, and the coupler key 29 is then inserted in itsposition. I

It will be noted that upon pull of the draw-bar the strain of the connection bethe yoke-strap is tween the draw-barand yoke-strap is upon the coupler key 29 and the clevises which are secured to the yoke-strap, and also upon the pins which directly connect the yoke-strap to the coupler, so that the pins 30 are under double shear. A firm and readily detach-- able connection between the draw-bar and v yoke-strap is thus provided, as well as one in vwhich the strains, either in pulling orbufiing movement of the parts, is welldi'stributed.

I. claim:

As an article of manufacture, a'detachable I connection fpr drawbar's and yokes of rail-- way draft mggmgs having the usual alined upper and lower sets of rivet receiving holes,

-said connection comprising two clevises, each of said clevises being provided on the inner face of the transverse portion thereof with a pair of integral, relatively short pins adapted rat to be extended through the adjacent upper or ower set of alined rivet receiving holes of he draw bar and yoke, said clevises having the side arms thereof arranged to overlap 5 .when in assembled position, the overlapped portions of said side arms being provided with alined slots adapted to receive a coupler key whereby the pins when the parts are in operative position, are placed under double shear. 10

In Witness that I claim the foregoing I have hereunto subscribed my name this 21st day of May, 1917.

WILLIAM A. GEIGER.
